Manila

The city was one of many on Earth that had lost land to the rising sea levels brought on by manmade climatic change.

In the early 23rd century, a ship-building contractor, Shimata-Dominguez Corporation, was located in Manila. (The Starfleet Museum: Paris-Class Light Cruisers, Lancaster-Class Cruisers)
